### 10 Good Video Sources for Math Students and Teachers

Earlier this week I shared ten video sources for history students and ten video sources for science students. To wrap-up the week I have a list of ten video sources for math students. Like the other lists, I've intentionally left out Khan Academy because everyone knows about that option.

WowMath.org is developed by high school mathematics teacher Bradley Robb. His YouTube channel has more than six hundred videos covering topics in Algebra and Calculus. You can access the videos on a mobile version of WowMath too.

Numberphile is a neat YouTube channel about fun number facts. There are currently thirty-three videos in the Numberphile collection. The videos cover things like 998,001 and its Mysterious Recurring Decimals, Pi and Bouncing Balls, and 1 and Prime Numbers. I've embedded Pi and Bouncing Balls below.

Bright Storm is an online tutoring service. On their YouTube channel Bright Storm provides hundreds of videos for Algebra I, Algebra II, Trigonometry, Precalculus, and Calculus. Bright Storm also offers some SAT and ACT prep videos.

Ten Marks is another online tutoring service that offers mathematics tutorial videos on their site as well as on their YouTube channel. Some of the lessons in their playlists include lessons on units of measurement, decimals, fractions, probability, area and perimeter, and factoring.

Math Class With Mr. V features seven playlists made by a mathematics teacher teaching lessons on basic mathematics, geometry, and algebra. In all there are more than 300 video lessons. Like most mathematics tutorials on YouTube, Math Class With Mr. V uses a whiteboard to demonstrate how to solve problems.

The Open University is one of my go-to YouTube channel for all things academic. A quick search on The Open University reveals seven playlists that include lessons in mathematics. The lessons that you will find in these playlists are more theoretical than they are "how to" lessons.

Yay Math! features an excited teacher teaching mathematics lessons to his students. The videos capture just the teacher and his whiteboard with some feedback from students. The videos cover topics in Algebra and Geometry. You can check out the Yay Math! companion website to learn more about Robert Ahdoot, the teacher featured in the videos.

Knowmia is a website and an iPad app for creating, sharing, and viewing video lessons. The website portion of Knowmia is a collection of videos made by teachers for students. There are roughly 10,000 videos in the Knowmia collection right now including lots of instructional math videos. Many of the videos are pulled from YouTube while others are hosted on Knowmia. The videos are arranged by subject and topic. Registered teachers can upload and tag their own videos.

Math Doctor Bob's YouTube channel was suggested by a reader using the Disqus ID Npisenti. Math Doctor Bob offers nearly 700 video lessons on statistics, algebra I and II, calculus, geometry, and much more. The lessons feature Doctor Bob giving the lesson in front of a whiteboard so you see him and don't just hear his lessons.

Patrick JMT Khan or Math Doctor Bob, but the videos are equally solid.

### 5 Good Places to Learn to Write HTML

This afternoon I received an email in which I was asked how to write a hyperlink without relying on the visual editor in Word, Google Docs, or your favorite blogging platform. While the visual editing tools will usually do everything you need, at some point you might want to beyond the limitations of WYSIWYG. It's then that you'll want know how to write and edit HTML yourself. These are three resources that you can use to teach yourself HTML. The instructions in these resources are clear enough that middle school students can use them on their own too.

A Beginner's Guide to HTML & CSS is a nice resource developed by Shay Howe whose resume reveals that he works on the user interface for Groupon among other projects. There are currently ten text-based lessons for beginners. Once you've mastered the beginner lessons you can try your hand at the advanced lessons.

Codecademy is a place where anyone can learn how to write code. Codecademy offers lessons in basic HTML and CSS. Codecademy's lessons in basic HTML start with the very basics of explaining what HTML is, what it does, and how to write the basics. There are seven progressively more difficult lessons that students can work through on their own.

Thimble is a free Mozilla product designed to help users learn how to write HTML and CSS. Thimble features a split screen on which you can write code and see how it works at the same time. On the left side of the screen you write your code and on the right side of the screen you instantly see what that code renders. The latest version of Thimble gives you the option to start from scratch or to modify sample projects. The sample projects include directions for writing code. If you write the code correctly, you will know right away. Likewise, if you don't write the code correctly, you will know right away. Some of the sample projects you can work with include webpages, games, and avatars.

w3Schools has long been my go-to place for quick directions when working in HTML. If I get stuck while working on a project, a quick visit to w3Schools usually reveals the help I need to get past a stumbling block. If you're brand new to writing HTML start with the introductory sections of w3Schools to learn the basics.

YouTube is another of my go-to places for tutorials on writing HTML and many other things. Whether you want an introduction to writing HTML or you just need a quick tutorial to get you past one little obstacle in your code, there's probably a video for you. Here's one very popular video for beginners.

### Updated Again - Best of Web 2013

This afternoon in Fargo, ND I shared an updated version of Best of the Web 2013. I just gave this presentation last month so there isn't too much different in this version, but there are some new things including Wideo for video creation and the Classtools SMS Generator.

### Slides and Outlines from my Presentations at TAIS

Yesterday, I had the privilege of giving four presentations at the Tennessee Association of Independent Schools' technology conference. It was a fun day of learning and sharing. The slides and outlines from my presentations are linked below.
